‘Escaping Isn't for Everyone’: Kurdish Smugglers’ Navigational Tactics at Checkpoints in Iran

Development and Change, EarlyView.
ABSTRACT This article examines how Kurdish smugglers navigate state and insurgent checkpoints in the borderlands of western Iran. Drawing on ethnographic research, it analyses two key navigational tactics: persin, a form of negotiated passage involving transaction, recognition and the contingent toleration of authority; and jimi, rendered here as ...

An Empirical Model for Optimal Highway Durability in Cold Regions [PDF]

, 2016
We develop an empirical tool to estimate optimal highway durability in cold regions. To test the model, we assemble a data set containing all highway construction and maintenance projects in Arizona and Washington State from 1990 to 2014.

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19

Policy Studies Journal, EarlyView.
Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Developing a Higher Performance and Less Thickness Concrete Pavement: Using a Nonconventional Concrete Mixture

Advances in Civil Engineering, 2020
During the last three decades, concrete pavement or rigid pavement became a widely used alternative of flexible pavement (asphalt pavement) at freeways and highways with high traffic of heavy vehicles, due to its durability, long life, and less need of ...

Marketization in Public Purchasing as a Route to Business Corporations' Institutional Power: The Case of Outsourcing Social Services in Israel

Policy Studies Journal, EarlyView.
ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.
